Wafer Seal

Wafer Seal

A small adhesive, shaped like a wafer, that holds the pages of a magazine or other periodical together when it is sent in the mail. A wafer seal may also be placed on an envelope. Its purpose is to ensure that one does not read the enclosed material without leaving evidence of doing so. It is also called a mailing tab.

If you continue beyond that point, you reach the supercritical phase, where you have something with the density of a liquid but many of the properties of a gas--no surface tension, low viscosity, the ability to diffuse into anything, including the bond that the photoresist forms with the semiconductor wafer surface.

Etsuro Morita, General Manager of SUMCO Production and Technology Division, said, "Our partnership with KLA-Tencor will help us to move to the next-generation of wafer manufacturing and beyond, where our customers are building nanometer-scale devices on substrates of a higher quality than ever before.

Available in both 200mm and 300mm wafer sizes, Integral Wafer utilizes SensArray's existing Thermal Map software application for data display and analysis and the BaseStation and CarrierStation for production deployment and storage.

Silicon-on-Insulator (SOI) refers to a substrate technology where an insulating layer is formed within a silicon wafer, isolating the thin top layer of silicon where the active transistors will be manufactured from the rest of the silicon substrate.

Separation-by-IMplantation-of-OXygen (SIMOX) refers to a technique used by Ibis for manufacturing SOI wafers where an oxygen implanter creates a very thin insulating layer within the wafer, just below a thin layer of silicon on the top of the wafer.
